holy crap this boss is annoying
four enemies, one of them always goes first and has something like an 80% chance to use an attack that is guaranteed confusion, AND steps in to heal the others immediately after they get injured (doesn't count as taking his turn either)
three of the four enemies, including the one above, are big damage-dealers, one of them to the entire party
the only option to revive a character revives them at 1hp so you have to coordinate with your other characters to heal
but the one guy who always goes first always ends up picking one of the two (revive-item-user and healing-item-user) to attack, usually with the guaranteed-confusion attack
when confused, your characters perform random actions instead of the ones you wanted, so you end up either wasting a rare healing item on an unconscious character, or using a rare revival item on a character who's going to get lightly tapped and die again right after that
so basically half your party's perpetually dead and one of the other two is always confused and then GAH this is the most frustrated I've been at a video game in a while
